Chapter 235： Big cow (below)

Guo Tailai once again announced his own pursuit in front of others. The last time was in front of Zhao Dong and Zhang teacher Cao, when he said that it was more limited because it was a topic triggered by the car, so Guo Tailai expressed his preference for the pursuit of performance. Now

In the same way, whether it is a racing car or something else, Guo Tailai still likes to pursue the ultimate in performance. And he told everyone about this idea, that is, let everyone understand this, when doing design, do the most extreme, do the best.

This titanium alloy woven ball shade is a showcase that shows Guo Tailai's exquisite processing skills, so that designers can know how to achieve the limit.

“Signed here?” The technician inexplicably signed his name on the side of the titanium alloy in accordance with Guo Tailai’s request.

The only person who knows Guo Tailai's intention is Lu Zhiming. The last time Guo Tailai was doing this in the factory that produced the gyroscope in the Southern Group. He believed that the finished product brought by Guo Tailai tomorrow must have this signature part, let everyone know that this is the titanium alloy that was taken today. .

However, Lu Zhiming did not intend to break it. He also wanted to see what Guo Tailai wanted to do with this.

Monocrystalline silicon wafers for making chips are also available, but they are housed in a closed box. The preservation of monocrystalline silicon also requires a very strict dust-free environment, unless it is in a dust-free production workshop or in a transparent packaging box, otherwise it is not visible to others. There are also materials for the package, but it looks ordinary. phase

For Guo Tailai's reputation in machinery manufacturing, he has no reputation in the chip manufacturing industry. Those who do the circuit board believe that if Guo Tailai can make a printed circuit board to draw the lines on the breadboard, he does not believe that he can use mechanical processing to create a chip.

That is to say, although those technicians in mechanical design have thoroughly recognized Guo Tailai, and even do not need to do any further tests, the people who play the game control circuit to play chips still have not fully recognized. However, the attitude is better. At least, on the mechanical side, Guo did not brag. "

Monocrystalline silicon, there is no way for you to sign. Guo Telai, who was very embarrassed to ask for the technician, said: "But I will make this chip small enough. "phase

For the sneering attitude of the past, everyone is now at least willing to give Guo Tai a chance to step down. Everyone just smiled and didn't say much. Even if Guo Tai came to the time, nothing could be taken out, and it would not prevent everyone from selectively forgetting. Have you ever tried this test?

Mi Feifei, who is still worried this morning, is now completely worried. After inspecting the leader of such a big head, and then Guo Tailai also revealed his identity as a master of finishing, the uneasy heart of the company’s new technicians seemed to calm down at once, but on a calm surface. Next, Mi Feifei clearly can detect a powerful impact of their own in the body, as if the next moment can set off an uproar. Guo

Tailai’s seemingly simple words explain the direction of the company and explain the future. Can't help but say that this Guo still has two brushes. member

The workers calmly returned to their respective seats, the work plan to do the work plan, the pull equipment list of the pull equipment list, and the honing project of the honing project. Guo Tailai left the company with titanium alloy blocks and monocrystalline silicon wafers, and went straight to the studio.

In the window of the office, Mi Feifei watched Guo Tailai take a taxi and couldn't help but dial a phone. When it was connected, Mi Feifei couldn’t suppress it and yelled on the phone: “Jiayi, do you know who I saw today? Do you know who came to the company today? The fat man Guo really has two Brush!"...

...

Back in the studio, Guo Tailai called and said to Professor Wang, and pushed the appointment time for two days. He did not spare any effort and began to work quickly. that

A titanium alloy woven ball shade is too simple. Guo Tailai only needs to control the nano robot to dig out the required shape little by little. Even if the size is more than twenty centimeters, as long as the exterior is hollowed out, the inside part will naturally fall down and be easily disposed of. After almost an hour or so, Guo Tailai completed the overall processing of the titanium alloy lampshade.

The processing precision is required to be a trace. How can Guo Tailai be so good? Therefore, according to the limits of their own capabilities, the processing accuracy is positioned at 50 nanometers.

To be honest, processing and making some metal parts, for Guo Tailai, in addition to the relatively large size is still somewhat challenging, other aspects are basically no difficulty. As long as Guo Tailai can produce a 3D rendering in his mind, the processing is just a matter of illustration. inverted

It is Guo Tailai's first contact with chip manufacturing today. It is very simple for Guotai, but Guo Tailai knows that it is far from simple. In that case, Guo Tailai can try a very small number of nano-robots to etch and etch a few chips, which can be manufactured on a large scale, or not at all, and can't be done at all.

Open the circuit design of the 8086, Guo Tailai looks carefully, and on his hand, a sealed box is being pinched in his hand. If someone can see through it, you can see that Guo Tailai's finger seems to grow a thin needle, pierced the sealed box and inserted it into the monocrystalline silicon wafer in the box. One

One transistor was etched by Guo Tailai according to the drawings he saw. Guo Tailai did it very carefully and the speed was very slow. It took about one second to etch a transistor. A total of 40,000 transistors, one chip etching, requires Guo Tai to eleven hours. Do not

However, the normal 8086 is a 3 micron process, and the Pentium 3 is a 250 nanometer process. The 8086 that is now produced by Guo Tailai is a 50 nanometer process. It is 60 times smaller than the normal 3 micron. In other words, the chip made by Guo Tailai is less than one millimeter in size. seal

The installation is also an extremely fine process. The etched single crystal silicon wafer is packaged and sealed, and the pins and chip contacts are connected by wires. Under the precision of 50 nanometers, the same one-point production is completed, and a A chip that is extremely long but has a size of less than one centimeter. system

In the process of the process, the whole process is closed, only the nano-robot is in contact, and the environment is completely dust-free. In order to make his technicians look more intuitive, Guo Tailai also spent more than ten hours deliberately making a bare chip, which is a hungry silicon chip without package. Those technicians can directly see the transistor with a microscope. structure.

Then Guo Tailai took these and went to the company again.
